Lay down first layer of 1/2-inch thick plywood or OSB with joints staggered in relationship to Soundmatt joints. Because an STC/IIC of 50 provides only marginal sound control, the International Code Council (ICC), author of the IBC, now recommends that an “acceptable” level of performance for both STC and IIC is 55 (52 if field tested). This is due to drywall’s larger mass and the fact that sound travels very quickly through wood. Understanding STC ratings for drywall can be complex. With IIC and STC ratings of 48 and 45, it’s ideal for floating engineered floors and for laminate flooring on plywood and concrete subfloors. Feb 19, 2024 · How is the STC Rating Determined?
